How to Rotate 3D Object using Accelerometer?

I'm trying to rotate a 3D shape (Cube) in Unity using an accelerometer. The goal for this part of my project is to have a Physical Cube with an accelerometer added to it, and when I rotate that cube, the cube on my Unity interface also rotates.

I'm new to using Unity so I don't know all the details. My team for this school project is using Unity, Arduino, and C#

I would appreciate any help or input on how I can perform this action
